How to Use This Manual

The Oracle Enterprise Manager Policy Reference Manual (hereafter referred to as the Policy Reference Manual) lists all the Oracle defined target policies that Enterprise Manager monitors. This manual compiles in one place all the target policy help available online, eliminating the need to have the Grid Control Console up and running.

Organization of Policy Text

This manual contains a chapter for each Enterprise Manager target for which there are policies defined by Oracle. The policies in each chapter are in alphabetical order according to category.

Policy Information

The information for each policy comprises a description, summary of the policy's main properties, default values, impact of the violation, and action to perform when the violation occurs. The following list provides greater detail:

  • Description

    Defines the policy.

  • Policy Summary

    Summarizes in table format the severity, category, target type, versions affected, policy rule evaluation, automatically enabled, and alert message statistics for the policy.

  • Defaults

    Lists the parameters with their default values and objects that are excluded by default.

  • Impact of Violation

    Describes the effect of the policy violation on Enterprise Manager.

  • Action

    Provides guidelines to follow once the policy rule is violated.

Definitions of Columns in Policy Summary Tables

The Policy Summary table is part of the overall policy information. The following is an example of a customary Policy Summary table.

Severity Category Target Type Versions Affected Policy Rule EvaluationFoot 1  Automatically Enabled? Alert Message
Warning Storage Database Instance Oracle Server 10g Release 1 or later The underlying metric has a collection frequency of once every 7 days. Yes Disk Group %DISK_GROUP_NAME% contains disks with different redundancy attributes. This may offer inconsistent levels of data protection.

Footnote 1 The policy rule is evaluated each time its underlying osm_diskGroup_Policies metric is collected.

The following table provides descriptions of columns in the Policy Summary table.

Column Header Column Definition
Severity Seriousness of the policy. Options are: Critical, Warning, and Informational.
Category Classification of the policy. Options are: Configuration, Security, and Storage.
Target Type Components monitored by Enterprise Manager, The target options are: Automatic Storage Management (ASM), BEA WebLogic Managed Server, Calendar Server, Cluster Database, Database Instance, Host, Listener, OC4J, Oracle HTTP Server, and Web Cache.
Versions Affected Version of the target, for example, BEA WebLogic Server 7.1 or later.
Policy Rule Evaluation Lists the underlying metric and that metric's collection frequency.
Automatically Enabled? States whether the policy is enabled upon installation of Enterprise Manager. The possible values are yes and no.
Alert Message Message indicating why the policy was violated. Words that display between percent signs (%) denote variables. For example, Disk Group %DISK_GROUP_NAME% could translate to Disk Group /dev/hda.

Background Information on Policies

A policy defines the desired behavior of systems and is associated with one or more targets or groups.

While a metric alert monitors data that is very dynamic in nature and attempts to evaluate how the system is performing, a policy monitors data that changes much less frequently. Policies evaluate the existing state of the system against corporate standards and best practices.

Accessing Policy Rules Using the Grid Control Console

To access the Policy Rule Library page that contains all the policy rules provided by Oracle, perform the following steps:

  1. From the Grid Control Console home page, click Policies.

  2. On the Policy Violations page, click Library.

  3. On the Policy Rule Library page, locate the policy of interest and click the Information icon (i) in the Description column. The help for the policy displays.

For additional information about policies, see the Enterprise Manager online help and Oracle Enterprise Manager Concepts.
